IMPROVED BU PiGLAFl-PROOF SAFE.

Specification forming part ot' Letters P atentNo. 2254i?, dated January 11, i859.

invented a new and useful Improvement in Burglar-Proof Safes 5 and l do herebyvdeclare that the following is a full and exact description thereof, reference being A'had to the accompanying drawings, making apart of this specication.

Figure l is a front view of the open mouth 'ot' my improved safe; Fig. 2,'a View ot' the upper end of said sai'e, and Figs. 3 and 4t are Sections in the lines am and y y of Fig. l.

Similar letters indicate corresponding parts in each of the drawings.

My improvement in burglar-proof safes consists in combining a rabbeted cast-iron doorframe7 a b, with the wrought-iron portions of the top, bottom, and sides of a safe in such a inannerthat the impenetrably hard molten iron which is afterward combined with the said-wrought-iron portions of the safe (b'y any suitable molding and pouring operation) will` ordinary tools.

The wrought-iron portions of the top, bottom, back, and sides ot' my improved burglarproof safe consist of the perforated double-casing plates cj', the exterior band, c, the inner angle-plates, t' t, the outer an gle-plates, d d., and the necessary rivets and screws to combine the said parts with each other and with the cast-iron door-framed b, as represented in the drawings. The outer casing-plates, f f, after being combined with' the angle-plates d d, are combined with the band c by means of the rivets g g, and the band c is combined with the door-frame by means of the screws 7L h.

inner casing-plates7 e e, after being properly riveted tothe angle-plates it', are combined with the door-frame. by means of the screws .7.?

b, on one side of the door-traine, into the recess within the same, for the reception ot' the lock-bolts, and nearly corresponding sockets nnmay be l'et into or cast with to opposite jamb of said door-frame for the reception ot' permanent projections on the inner edge of the sate-door, The apertures in the casingplates e j' are ot' the outwardly-daring shape represented in the drawings. It will therefore be perceived that when the molding sand is made to close the apertures of the casing-plates flush with the exposed surfaces of the same and the melted iron is poured into the space between said plates that it will also fill up the flaring apertures in the same7 and as it hardens it will inseparably connect the said plates with each other. The said melted iron (which is represented by red ink cross-lines lo in the drawings) will "also now into't'hc space within the jambs ot the door-frame and into the space between the rabbet of the door-frame and the band c7 and as the said melted iron becomes chillhardened in cooling the combination ofnietals which will then surround the door-frame of the safe will be of such a nature that they will resist every effort to break through the same and uncover the door or its fastenings' that human ingenuity can by any possibility bring to its-assistance in furtherance of such an object. y

l. do not intend to limit myselt` to any parcast door-frame, substantially as herein set The 1 forth.

Having thus fully described my improvement in burglar-proof safes7 what I claim Sockets m m may pass through the jamb therein as my invention, and desire to secure said door-frame, substantially as herein set by Letters atent, is- 1 forth.

Combining,` n, cast-iron door-frame with the The above specification of my improvement nought iron portions of the frame of a safe i' in burglar-proof safes signed and witnessed, in suvh a manner that the moten iron, which JOHN l-, GCRNELL. is afterward, While in a meited state, coni-v; Vitusssos:
